Correct. There is no point telling the others that there is a second chance when in fact the chance is so small. Most of the time, you are not going to hit the 1/1000. If we tell them that there is a second chance, they are not going to get serious and instead will just think that: "Oh I messed up? No big deal, I can just go running around and I'll find it." Maybe hours later they will return empty-handed and complain that the second chance is not reliable, if not outright criticizing it to be a big lie.

Perhaps I forgot to mention, some other players will also get mistaken that the second chance means just leaving and re-entering again, then the Pokemon will return to their original spots, which is obviously false for the Set Encounters.
